Background Young, active, skeletally mature patients have higher failure rates after various surgical procedures, including stabilization for shoulder instability and primary ACL reconstruction. It is unclear whether young, active, skeletally mature patients share similarly high failure rates after revision ACL reconstruction. Questions/purposes We therefore determined whether revision ACL reconstruction restores knee stability and allows young (younger than 18 years), active, skeletally mature patients to return to preinjury activity levels.
Patients and MethodsWe retrospectively identified 36 patients who had an initial ACL reconstruction between the ages of 12 and 17 years (mean, 15.4 years) and subsequent revision between the ages of 13 and 18 years (mean, 16.9 years); of these, 2-year followup was available for 21 (75%). Mechanisms of primary graft failure included traumatic rerupture (23 noncontact, seven contact), persistent instability (five), and infection (one). One patient had open physes at the time of revision. All revisions were single-stage transosseous reconstructions. The minimum followup was 24 months (mean, 36 months; range, 24-63 months).
